I use an attachment to the drill that cuts metal. About 8 to 10 bucks when I bought it. Two, I use rivets. Simply drill a small hole, add the rivet then pop it. I would round the holes where that filter goes in too. Those rivets make it a lot more sturdy and are very inexpensive. The rivter was about 15 bucks.
fresh out of school and still have a lot of questions, but slowly everything is clicking into place, Thank you Tad!
same here
undersized return can affect refrigerant pressure. Another thing I learned. Really cool. No pun intended..
Very cool brother you're right
Is this Chattanooga?! That’s where I’m from and I’m in my first year of HVAC love your videos, they help a lot!
I'm in tennessee about four hours of Chattanooga
I have a problem in heating mode where the flame is rolling out due to no having enough airflow
What should you do in case of a gas water heater next to the furnace? Can you split the existing return ductwork and tie it to the other side of the furnace? Will it increase airflow?
I also have a hot water heater next to my furnace, like in one of the questions before. Can I split the existing duct return and tie it to the other side of the furnace. Will this work? Will air flow increase?
definitely recommend turbo sheers ...save so much time
I have a pair they are amazing
Attach right to my drill
@@TaddyDigest there a must have for this industry
16 INCH ROUND IS GOOD FOR 1400 CFM, I HAVE THE SAME SENERIO. I REALIZE MORE RETURN IS BETTER BUT, DO YOU COUNT THE SQUARE INCH OF THE RETURN VENTS OF THE DUCT SIZE OR BOTH. EXAMPLE, ALL MY RETURN VENT ARE CLEARLY MORE THAN REQUIRED FOR 1400, BUT, MY RETURN DUCT JUST BEFORE MY 14OO CFM RETURN PLENUM IS A LITTLE
Wouldn't this cause suction pressure and head pressure to rise since your adding all that heat from the garage into the system?
Well, they are insulating the garage and turning it into a room, so it's going to be conditioned
Use a muti tool with carbon blade works good keep the blade at an angle.
imo this was a bad idea...ur taking to much return air from that basement area and not the living area...u should have tied the return into the living space some how..u can never have to much return but u want it from the space ur conditioning
I agree
That's right 👍.
For a 3.5 ton unit shouldn't you have the unit operating at 400 cfm per ton on the furnace control board?
Yes that would be ideal
Can the system ice up with too much return? I've seen two returns on a 2.5 ton 16 and 14 flex on it.
Not enough return will cause it to freeze up
Where can I purchase the angles used for the air filter rack installation?
distributor/supply house or online
Is it ok to install a return in a garage? Isn’t there a chance for it to pull in carbon monoxide? Or is that considered a basement with a walkout garage looking door? Thank you Tad
it's never ok to install a return in a garage
unless the house it being remodeled and the garage will be a room instead
If my furnace has a 5 inch, Merv 11 filter, do I need to add air filter on 20"x24x1" return vent?
not sure
I do not know what size your ductwork or your unit is
@@TaddyDigest they are about 18-20 inch in diameter
id just put a filter base on the side...quick and done
Just to let you know is Actually 500 CFM’s times two for that 20 x 25 because theres 2 CFM for every one square inch of filter space…so you really only need 200 hundred more cfm
Maybe 3 tops👍
That is absolutely correct
Never mind you said 700 sq in, I didn’t catch that part 🙏🏽
I've got a crazy question. What happens if a kid pulls the filter and sticks their hand in the running fan?
my furnace doesn't have a return, just open air then filter. do I need a return?
Having a return centrally located in the house will give you better comfort and efficiency for the equipment.
Hey Teddy. No offense, but I cant believe my eyes that you posted it 😂. 1) Fire the guy, who put the screw towards the filter rack. He couldnt put the filter himself, how could the customer slide it in? 😉 2) Is it allowed in your state to put the return in the garage? (Risk of sucking car exhaust gases) 3) wont there be a negative pressure in the garage and positive pressure in the house?
They don't park cars in it
I love my James He is awesome
Thanks for looking out for me
There is one supply vent in there
@@TaddyDigestthanks for the clarification 😁👍
That would never pass any code or inspection, especially when they go to sell the house. Hot ass air from the garage being used for return air regardless, if there park in there. That is what a hack does and an inspector would have a heart attack. I told you I would be around more. This is the kind of crap I expect from a hack of a DIYer. I hope nobody ever follows your advice or they will be in some trouble some day. Garages have far more than just exhaust fumes. All returns must come from inside the conditioned space when the air handler is installed in a garage or building that isn't livable space. There is no way you are EPA 608 or NATE certified. I bet you don't even have business liability insurance. Garbage work and can't even follow simple code and rules.
I'm glad you're around
Keep reading those books buddy
Sometimes you gotta do what you gotta do for the unit to work and for the customer to have heat and air.
But I guess you wouldn't know am I right to assume?
Let me know thanks for watching
Absolutely you're welcome my friend and thank you for looking out for me again
As a licensed general contractor, I totally object to this practice, and any competent building inspector flag this as an egregious code violation. A garage is NOT a good place for a cold air return. It will positive pressurize the house at a large energy penalty unless there is a jumper duct from the house to the garage or there is an appropriate amount of supply ductwork conditioning the space in the garage, which in this case would be far too much for the space. Either way, they are creating unhealthy indoor air. For fire separation and safety, GARAGES SHOULD BE TOTALLY SEPARATED AIRSPACES FROM HOUSES, ESPECIALLY IF THEY HAVE CARS PARKED IN THEM. Read up on the ICC rules for garage construction if you doubt this. Far too often, HVAC work is about fixing something horrible by doing something bad. I am a general contractor tired of the abysmal standards of HVAC industry. Just because the air handler blows harder with this quick fix does NOT make the overall system more efficient, and it is unhealthy to mix garage and indoor air. Sometimes, partial knowledge is worse than complete ignorance.
I agree that's why in this video I explain that this is not being used as a garage anymore.
Homeowner was remodeling and removing garage door and closing it in to make it a conditioned room.
Thank You for sharing this knowledge
Hot water heater??? 🙂
Great idea in theory but your not supposed to put a return in garages because of automobile combustion gases could enter house which means s a extremely dangerous hazard. Where I am the would be a code violation but more importantly the potential hazard is more of a concern.
You're right
In this particular instance
The customer is closing in the garage and using it as a room
@@TaddyDigest I’ve watched enough of your video to know you do things correctly and to a high standard so I was pretty sure you weren’t doing anything unsafe but not all that watch know these things and it could be an issue if someone does that without being well informed.
You still available for questions??
Always
@@TaddyDigest I know this would help supply and supply is my issue some but mostly return is my issue. Can I use this method to connect it to a drop down coming from the existing duct run?
@@TaddyDigest I have a 6×20 return doing the whole house on a 3 ton 1200 CFM house return is horrible.
@@TaddyDigest The whole return duct run is 28 ft with 5 return vents that go through floor joist/forced air..
Yeah you should be able to use this method
